On my drives, setting the signal gain to give the required speed in relation to the input signal is the last thing to do. For my system, the object is to arrive at a table speed of 300 ft/min with an applied command of +-9V (leaving some head room). I increase the command signal in small increments (from about 0.2V) and measure the table speed, adjusting the signal gain to obtain the desired relationship and adjusting tach gain to give the shortest settling time without overshoot.
You should be confident that the motor will behave in a predictable way to avoid the ever present danger of a high speed run away (with the possible consequence of machine damage or personal injury). If you have doubts, uncouple the motor.
